As we know, terrorism is one of the biggest problem in the world. More and more people become the terrorists. Some want money. Some want to do the dangerous things. Some like to kill people. The only thing I want to say is that their brain is broken. Their brain must receive some bad things. But textbooks can solve this problem. If the publisher add more bad things about terrorism and knowledge about not being a terrorist, the text book can teach people from teenagers and children to the adults. And more and more people will realize that being a terrorist is not a good road to walk. For the world, for the future of people, this idea is really important.
